Stability analysis and anchorage design of slope block in the Xinsanfei Slope
The working zone is on the edge of Longmen mountain tectonic zone, with a complicated regional structure and the NE-NEE direction of regional tectonic line. The overall height of slope is about 70 meters high and the.surface of slope is cracked. There are plenty of half-certain blocks and random blocks during the excavation of the slope. The stability of these blocks has important impact on the slopes security. This paper is to calculate the stability of blocks in specifically nature, earthquake and blast conditions, and evaluate the stability of the local block in different parts of slope and sum up optimal anchor length, based on the engineering geological conditions of the slope and the engineering geological characteristics of structural surface, using Stability Analysis of Slope Wedges software (SASW), combining block theory, vector analysis, permutation and combination, analytic geometry of space and modem computer technology, establishing the complex geological model with cutting method. Finally, the analysis of the sensitivity factors of the block stability help to the actual construction.
